$\cot^{2} (x) \csc^{2} (x) - \cot^{2} (x)$

Step 1

Reorder $\cot^{2} (x) \csc^{2} (x)$ and $- \cot^{2} (x)$ .

$- \cot^{2} (x) + \cot^{2} (x) \csc^{2} (x)$

Step 2

Factor $\cot^{2} (x)$ out of $- \cot^{2} (x)$ .

$\cot^{2} (x) \cdot - 1 + \cot^{2} (x) \csc^{2} (x)$

Step 3

Factor $\cot^{2} (x)$ out of $\cot^{2} (x) \csc^{2} (x)$ .

$\cot^{2} (x) \cdot - 1 + \cot^{2} (x) (\csc^{2} (x))$

Step 4

Factor $\cot^{2} (x)$ out of $\cot^{2} (x) \cdot - 1 + \cot^{2} (x) (\csc^{2} (x))$ .

$\cot^{2} (x) \cdot (- 1 + \csc^{2} (x))$

Step 5

Rearrange terms.

$\cot^{2} (x) \cdot (\csc^{2} (x) - 1)$

Step 6

Apply pythagorean identity.

$\cot^{2} (x) \cdot \cot^{2} (x)$

Step 7

Multiply $\cot^{2} (x)$ by $\cot^{2} (x)$ by adding the exponents.
